16 Claims.

\ This invention relates to an improved washer placing machine, and more particularly to a machine of this kindwhichis adapted for use in Vplacing nailing washers on the pins of lrubber heel producing molds.

fAn object of the invention is to provide an improved Washer placing machine having novel washer feedingmeans including a main finger pivoted for lateral swinging movement rand a second finger carried vby the main linger and adapted for lateral swinging movement relative thereto. v

Another object of the invention is to provide a Washer placing machine having a novel arr rangement of washer feeding fingers including a pair of fingers adapted for relative lateral swinging movement and interconnected by proportional movement mechanism.

1 A further object of the invention is to provide an improved washer placing machine having a frame with a member thereon movable about pivot means extending transversely to the longitudinal axis, and wherein washer feeding fingers' carried by such pivoted member are adapted for relative lateral swinging movement and are interconnected by proportional movement mechanism.

. Still another object of the invention is to provide an improved washer placing machine having a plane-like or foot-like frame with a novel arrangementof washerfeeding fingers thereon.

Otherfobjectsand advantages .of the invention willibe apparent from the following description, 'when takenin conjunction with the accompanying sheets of drawings, wherein- Fig. 1 is a top plan view, with portions broken away, showing a washer placing machine embodying my invention. w

Fig. 2 is a longitudinal sectional view thereof taken on line 2--2 of Fig. 1. v

Fig. 6 is a sectional view taken through one of the main washer feeding iingers as indicated by line (--S of Fig. 1.

More detailed reference will now be made to the accompanying drawings wherein l have vshown one embodiment of Vmy improved washer placing machine. It will be understood, of course, that the machine shown in the drawings is by way of example only and that the invention maybe embodied in various other machines andapparatus Aoi" this general type.

, zAs shown inthe drawings, ymy improved washer of a movable member 22.

placing machine may be provided with a planelike or foot-like body I which forms the frame ofthe machine and supports a plurality of washer feeding devices or fingers I I, I2 andI3. During use of the machine they body I0 is manually, or

otherwise, moved over a mold member having projecting pins, and during such ymovement washers are automatically placed on the pins by the fingers. Y

l The frame I0 may be provided with a substantially flat bottom plate which, in general appearance and outline, may correspond roughly with the sole of a shoe or the bottom plate of a plane. The heelend of the frame, which is also the forward or leading end, may be constructed with a hollow part I which houses certain nger carrying mechanism to Ybe described hereinafter and provides a connection for an operatinghandle I6. It will be understood, of course, that the bottom plate may be formed integral with the frame I0, or for convenience of manufacture, may, as shown in this instance, be formed by plate sections I'I and I8 which are connected to the bottom of the framey byscrews or other suitable fastening members. The plate section I'I is preferably of a size,

and-shape to form a cover for the bottom of the hollow frameV part I5. The plate section I8 has an opening I9 therethrough in which the fingers Iland I2 operate and an opening L2li in which the iinger or device I3 operates. Frame portions 2I extend rearwardly from the hollow part I5, that is toward the toe end 2|',and form an upstanding liange around `the openings VI9, vrand 20.

For operably mounting the fingers II and I2 I may provide a finger carrier which is in the form K As shown in Figs.V 1 and 2 the member 22 maybe a frame-like part which is disposed in the hollow body part I5 and which is mounted for vertical rocking movement by pivot means extending transversely with respect to the longitudinal axis of the machine. The pivot means may be in the form of screws 23 extending throughthe sides of the frame I0 and having pin projections 24 upon which the member 22 is fulcrumed. v V v The member 22 may be constructed to include a ,transversely extending bar portion 25 into which the pin projections 244 extend, and may also, include spaced arms 26 *whichl extend forwardly from the bar portion 25 towards an opening 2l ln the end wall of the hollow frame part I5. The arms 26 may be connected by another bar portion 28 which extends transversely of the `machine just inside of the opening 21. From the arrangement just described it will be seenY that the member 2.2 is pivoted on the frame I0 for swinging or rocking movement in a vertical `plane and about the pivot axis provided by the projectionsv 24.

which extend, respectively, abovel and below the Y bar portion 25 of the carrier. The washer feeding finger I2 may have a similar pair ofvertically spacedA supporting arms 32 and 33 .which also extend, respectively, rabove andbelowvthe bar 25. The arms 30 and 3i of the finger II and the arms 32 and 33 of the finger I2 Y are spaced apart vertically substantially 'the same distance,

but the arms 32 and 33 are vertically ofi-set'soV as to extend over the arms 30 and 3| in crossing relation thereto adjacent the transversefbar portion 25. A vertical pivot pin 34 carried'by the transverse; bar portion extends through the pairsofarmsof the fingers II and I2 at their crossing points andv provides a pivot upon which thesehfingers have lateral swinging movement.v The pairs of arms have bearing cooperation withV each other and with the transverse bar portion 25 sovthat the fingers II and I2 are supported thereon Vand haveflateral swinging movement `about the pivot pin 34 in substantially the same horizontal plane. n

As a feature of my invention I provide proportional movement mechanism interconnectingrtheV fingers II and I2 so that when either Vfinger is swung laterally of the frame I0 the other finger will be moved substantially proportionately therewith. This proportional movement mechanism may be located forwardly of the pivotrpin 34, that ison the side thereof opposite to the ngers II andV |2`, and may .includev a pair of projecting lever Yarms 35 and 36. may be an extension of the finger supporting arm andthe lever v3I5 may be an extensonof Vthe finger supporting arm 33.L 'A longitudinally extending guide member, preferably in the form of a pin or rod 31, may be connected withV theV bar portion 25 to extend forwardly therefrom through a threadediopening of the transverse bar portion 28 and also throughV the opening 21 of the hollow frame portion I5. A guide block or member 38 Imay be mounted on the rod `31 for sliding movement therealong.V The upper 'end of the Vguide block V38 may be connected with'theglever arm 35 by a` link 39 and the lower end of this guide block may be connected with the lever arm 36 by a similar link 40. From the arrangement just described it will be seen that Ylateral swingingfof either the finger II or the finger I2 Vwill cause movement to be transmitted from one finger to the other through the lever arms 35, 36,Y the links 39, 40 andthe guide block 38. Swinging of the fingers II and I2A towardV each other,'that isinwardly toward the longitudinal axis of the machine, will cause the guide'block-38 to'moveforwardly along therrod 31 toward the opening V21 of the frame. ,Separating movement of the fingers II and I2, that is movement thereof away from the longitudinal axis, lwillV cause the 'guide block 38 to be moved along the Vrod`31 toward the pivot pin 34.

I prefer to have the kfingers II Vand I2l in norfmally separated or divergent relation, as shown in Fig. 1,'and to this end I may` provide acompression spring 4I which may beV disposed Yaround the guide rod31 to pressfagainst the guide Yblock `38. adjustable abutment 4for the spring, 4|

ing accommodating the guide rod 31. The screw 42 may extend outwardly through the frame.

opening V21 as a manuallyY operable adjusting member which is accessible from the outside of the hollow frame part I5.

The bottom plate section I1 of the frame may be provided with a'pair of Y flanges 43V depending therefrom on` oppositersides ofthe longitudinal .tively, rwith depending flange portions 44 and 45 which normally extend in diverging relation similar to the diverging relation ofthe fingers themselves.V These flanges -44 and 45 of the fingers start adjacent the rea'r end 'of Vthe channel'forming fianges 43,'a'nd this starting point isV adjacent the axis of the vertical pivot pin 34.'.As the machine is moved over the mold with'certain rof the pins engagingV in the channel formed bythe depending fianges 43, Yother mold pins will strike the anges 44 and 45 'and Vwill cause llateral Yswinging ofthe fingers II and I2 vsufficient to direct the mold pins into proper cooperation with Vthe washer feedingmeans'of these fingers.

TheV bottom .plate section I8 may also be provided with Vdepending flanges 46 defining a .guide channel '46' which is aligned with the guide channel-formed by the flanges `43. The Ypins which engage in the channel 43' also engage in the channel formed bythe flanges 46 and are directed thereby to the washer feeding device I3.

As another feature of my invention I Vprovide Veach of the main washer feeding fingers 'II and kI2 with a second or auxiliary washer feeding'finger, the auxiliary finger for the main finger II being the fingerj41 and theauxiliary finger for the main finger I2 being the finger 48. As seen an intermediate point thereof. The finger 41 is pivotallyconnected with the lmain'fing'er II by suitable pivot means 43 which permits this finger to swing laterally'outwardly relative to the main finger; Similarly. the finger 48 fis connected with the main finger I2 by pivot means 50 which permits the auxiliary finger to swing outwardly Such outward swinging of the auxiliary fingers 41V and '48 is desirable because it permits these fingers to cooperate with mold pins which are spaced outwardly from the mold pins with which the main fingers' II and I2 cooperate. Y Y

Each of the. washer feeding fingers II, I2, I3, 41 and 48 includes an escapement through which washers are permitted to be individually drawn bythe mold vpins 'as the 'fingers move'thereover, but which prevents lwashersfrom dropping o'ut of the fingers at other times. This escapement Vmay be of similar construction for each of the fingers and, thereforaonly one escapement will be `described in detail. The escapement may comprise Ya pairfof cooperating members 52 and 53 bothof which are movable relative to the finger V,o'nfwhich they are supported* The member 5'2 is a washerguiding member and, as such, has

'cal cross-section to 'which-a Yseries or Stack of 4channel l54 `vby 'engagement o'fthe lowermost 1.15

' in'l Fig. 1 of the drawings the auxiliary fingers 41 .51ctv 51 between its shoulders-55. The-not ofthe member 53 directs the mold'pininto the central opening` of the lowermost washer so that the washer will be impaled on the pin. Y

.The member 53.1includes an inclined part 58 infwhichthe slotl57 is formed and which is en- Y gaged by,"and tilts, the lowermost washer so that the opening of thiswasherf will be presented to the mold pin. This membera'lso includes a forwardly extending' stem part 59 which is slidable on the lower part of the finger. `The member 52 is supported on the finger and connected therewith by atransverse pivot 60 which permits swinging of :this member in a direction to move the bottom end of the guideway 54 toward or from the member 53;, .The member 52 may be provided with depending lugs 6| at opposite sides thereof Vwhich engage inv recesses of the member 53. These lugs` assist in retaining the member 53 in properlyY ,aligned relation to the member 52.

11n" The supply of Washers may, as already mentioned, be in the form ofVv a series or stack extending=above the escapement member 53. Such a stack of washers maybe provided for each finger. and maybe retained in the ldesired regular order by a guide wire 62 upon which the washers are strung.y The wire may be suspended from the :upper end of a bracket 63 which is carried by the escapement member 52. 1

When the escapement device'of one of the fingers passes over a mold pin, the pin engages in the opening of the lowermost washer and displaces this washer from the` stack. This action is carried. out bythe pin pulling the washer out between the members 52 and 53. Sufficient space for the withdrawal. of the washer is provided by lifting of the member 54 on its pivot 60 in opposition to the spring 64 and accompanied by limited-shifting ofthe member 53. As the washer Amoves out from'beneath. the member 52 the top of the mold'pinpas'ses through the slot 56at -which time the depending, portions 65 forming the sides of this slot hold the washeron the pin.

'l From the construction and yarrangement of the fingers! l I2, 4'!` and 48 and the mounting means provided therefor',`it will belseen that these fingers being carried by the member 22 have more or less movement in a vertical plane by reason of the member being mounted on the transverse pivot means 24. At thesame time the main fingers` Il and I2 have Arelative lateral swinging movementv on their pivot pin 34 and the auxiliary fingers 41 and 48'on their pivots 49 and 50. By reason of these lateral and vertical movements it will be seen that as the machine is moved over theA mold, the fingers canV readily accommodate themselves to mold pins of varying height and of variable lateral spacing. The movement of the member 22 and ofthe fingers in the vertical plane may be controlled by providing a compression spring 66 which acts upon a portion 61 of the member 22 and a flat spring 58 which acts on the transverse bar 28. yThese springs act in a direction vto normally depress therfingers so that a desired positive. engagement with the kmold pins will always be obtainable. If desired, a stop screw 69 may be provided for cooperation with the bar part 28 for determining and adjusting the lowermost position of the fingers relative to the bottom plate of the machine.

The auxiliary fingers 41 and 4B which, as above explained, are caried'by thev main fingers' fll and I2 and have pivotal connection therewith, may benormally urged toward the main fingersby means of spring 89.v These springs may betensionl'springs extending between and connected with the upwardly extending brackets 6370i the main and .auxiliary fingers.'l Eachof the auxiliary fingers 41 and 48 may also be provided with Ya Wing-like projection 'Ill on thefescapement member 53. This `wing projection is adjaoent'the Youter edge of each auxiliary. finger `and extends outwardly 4away from the depending flanges44 and 45. As the machine is moved over the mold, certain. of the pins vwill engage these `outwardly extending wings or fianges 10 and cause the auxil- .'2

iary fingers to be swung relative to'ithe main fingers so that these mold pins will be directed into the slots. of the auxiliary fingers to withdraw Washers therefrom. .f v

For yieldably supporting the machine on the mold plate I may provide the frame with a pair of laterally spaced rocker arms 1l. These rocker arms are pivoted on the frame by means of` pivot screws 'l2 and have lever portions i3 towhich tension springs 'I4 are connected. The engagement of the rocker members 'Il with portions of the mold prevents lateral tipping of the machine while it is being moved over the mold pins. and also causes fiexing of the springs 14 to yieldably support the leading end'of the machine on .the mold. y

From the foregoing description and the accompanying drawings it will now be readily seen that I have provided an improved washer placing machine having a novel finger *arrangement* and finger supporting means, by virtue of which the fingers have both vertical and lateral swinging movement. It will also be seen kthat inV my inff proved Washer placing machine certain of the fingers are in the form of auxiliary fingers carried by main fingers and that this arrangement contributesto the simplicity of construction and the satisfactory operation of thev machine. While I have illustrated and described my im'- proved washer placing rnachinein-v a somewhat detailed manner, it will be understood, ofcourse,

that I do not wish to be limited to tneprecise de tails and arrangements illustratedfand described,

but regard my invention as including such changes and modifications as do not involve a departure lfrom the spirit of the invention and the scopeof the appended claims. l
